昨天晚上同学有个项目需求要实现在鼠标放上链接后显示层,离开后隐藏层,麻烦的是当鼠标放上层后,这个层会一直显示,离开这个层再次隐藏,今天中午趁着上班时间还没到,简单的测试了一下,成功了,具体原理就不细说了,请看源码:
<body> <a href="javascript:voie(0)" id="atest" onmouseover="a_onmouseover()">鼠标放上测试</a> <div id="divTest" style="display: none; background: red; width: 100px"> 我显示出来啦!!! </div>
<script type="text/javascript"> /* *Data:2009/12/11 *Author:董广祥 */
var timer; function a_onmouseover() { var ddv = document.getElementById("divTest"); var atest = document.getElementById("atest"); ddv.style.display="block"; ddv.onmouseover=function(){ clearTimeout(timer); ddv.onmouseout=function(){ this.style.display="none"; } } atest.onmouseout=function(){Mout()} } function Mout() { timer = setTimeout(function(){document.getElementById("divTest").style.display="none";},100); }
</script>
</body>
